Question

. From the ground H=0.8 M above, 0= 40° along the slope at an angle mass m 0.6 kg the block is released from rest. The coefficient of static and kinetic friction between the block and the slope is 0.5. The block slides downhill.

1)How much potential energy J is lost?

Answer 1

The potential energy lost is 4.7056 J.

Step-by-step explanation:

To calculate the potential energy lost, we need to determine the initial potential energy and the final potential energy. The initial potential energy is given by the formula PE = mgh, where m is the mass, g is the acceleration due to gravity, and h is the height above the ground. The final potential energy is zero because the block is at ground level. Substituting the given values, we get PE = (0.6 kg)(9.8 m/s²)(0.8 m) = 4.7056 J. Therefore, the potential energy lost is 4.7056 J.
